Two blocks are connected by a massless string over a pulley, as shown at right. Block A has a mass of 20 kg, and Block B has mass m. The coefficient of static friction between Block A and the horizontal surface is μs = 0.30 and the coefficient of kinetic friction between Block A and the surface is μk = 0.20. The mass m of block B can be selected to be any value between 0 kg and 40 kg. The value of m is chosen, and the system is released from rest. This is repeated for many different values of m. 6) On the axes provided, graph the friction force Ff acting on block A vs. the mass m of block B. Note the value of important points on the graph such as discontinuities, maxima, and minima. Show your work.

Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.

In the figure below, the mass of block A is 25 kg and mass of block B is 40 kg. The coefficients of static friction are 0.6 between blocks A and B, 0.2 between block B and the floor, and 0.5 between the rope and the fixed drum. Determine the minimum mass, m, of the weight suspended from the rope right at the point where first motion occurs. You may assume that the rope is aligned parallel and perpendicular to the floor, and that neither of the blocks will tip. Hint: You need to consider two sliding cases, calculate minimum m for each, and pick the smaller m of the two.
